Verizon has lowered their unlimited data plan from $45 to $30 per month for several of their PDAs. Call verizon or check online to find out if your phone qualifies for the lowered price.
If your PDA is not yet added it probably will be soon. You may want to check again in a few days.
Below is a list of PDAs which have been confirmed compatible with this new plan
i760
700Wx
SMT5800
XV6800

The $29.99/month unlimited plan does not support Exchange, which should primarily impact enterprise users. The new data plan will provide unlimited access to the web and up to 10 personal e-mail accounts, including free Internet email providers such as Windows Live, AOL and Yahoo.
Are you tethering? Under this new plan tethering goes from $15 a month to $30. If you want to tether for free with this new plan, GOOGLE IS YOUR BEST FRIEND.
Here is the list of smartphones that were turned down for this promotion.
700W (note that 700Wx is ok for discount ... go figure)
